The reaction manifold exhaust port 104 and the muffler feed pipe 131 are connected so that they are aligned. The reaction manifold exhaust port 104 and the muffler feed pipe 131 can be connected by welding or using the appropriate fittings.

A centerline 400 of the reaction manifold exhaust port 104 and the muffler feed pipe 131 will act as the reference axis for the invention 100. The direction of the centerline 400 moving towards the muffler 132 is referred to as 0 degrees. The direction of the centerline 400 moving away from the muffler 132 is referred to 180 degrees.

The first reaction manifold intake port 102 and the second reaction manifold intake port 103 are pipes that feed exhaust gases 300 from the first catalytic converter 112 and the second catalytic converter 122 into the reaction manifold exhaust port 104. The first reaction manifold intake port 102 is connected so that a first angle 401 formed by the centerline 400 of the first reaction manifold intake port 102 and the reaction manifold exhaust port 104 is 135 degrees. The second reaction manifold intake port 103 is connected so that a second angle 402 formed by the centerline of the first reaction manifold intake port 102 and the reaction manifold exhaust port 104 is 135 degrees. Relative to each other, the first reaction manifold intake port 102 and the second reaction manifold intake port 103 are placed so that their respective centerlines are on the same plane and the angle between them is 90 degrees.

Detailed reference will now be made to a first potential embodiment of the disclosure, which is illustrated in FIGS. 1 through 3. As shown in a first potential embodiment that is illustrated in FIGS. 1 and 2, exhaust gases 300 are drawn through the first exhaust intake port 111, second exhaust intake port 115, third exhaust intake port 121 and fourth exhaust intake port 125. The first exhaust intake port 111 and second exhaust intake port 115 feed exhaust gases 300 into the first engine manifold 114 routes the exhaust gas 300 to the first catalytic converter 112. The third exhaust intake port 121 and fourth exhaust intake port 125, which routes exhaust gases 300 into the second engine manifold 124, and which routes the exhaust gas 300 to the second catalytic converter 122. The first catalytic converter 112 processes the exhaust and expels the processed exhaust gas 300 into the first feed pipe 113, and which routes the exhaust gas 300 to the first reaction manifold intake port 102. The second catalytic converter 122 processes the exhaust and expels the processed exhaust gas 300 into the second feed pipe 123 which routes the exhaust gas 300 to the second reaction manifold intake port 103. From here, the processed exhaust gases 300 flow through the reaction manifold 101 into and the muffler feed pipe 131, the muffler 132, and the exhaust pipe 133.

A second potential embodiment is illustrated in FIG. 3. In FIG. 3, a third engine manifold 127 and a fourth engine manifold 128 are shown. In the second potential embodiment the third engine manifold 127 performs the same function of the first engine manifold 114 and the fourth engine manifold 128 performs the same function as the second engine manifold 124.
